Milling, Turning, Drilling

In this session, I introduce the fundamentals of metal machining, focusing on milling, turning (lathe work), and drilling, starting with the core concepts of cutting feeds and speeds [00:20] and the materials used for tools, such as carbide and high-speed steel. I explain that cutting speed is how fast the tool touches the material, while feed is how fast the tool moves through it [01:30], and also discuss the pros and cons of up milling versus down milling [03:00]. For turning, I detail the main components of a lathe, including the chuck, collet, and tailstock [04:47]. I then move to the different types of milling machines, distinguishing between vertical and horizontal mills [08:05] and describing advanced multi-axis machines like 4th and 5th axis mills [10:14]. Finally, I cover drilling tools and processes, including the standard twist drill [14:15], boring to achieve a better circular tolerance [15:52], reaming to smooth a hole [17:07], the use of a center punch to prevent drill wandering [19:36], and the various types of taps used for making threads [20:10].
